ANCHOB-CABLE-CUTTING APPARATUS FOR SUBMARINE BOATS.

Specification of Letters Patent.

Application filed Hatch 8, 1915. Serial N 0. 12,832.

for cutting the supporting cables of anchors carried by submarine boatsso as to release the anchors in the event of accident to the boat, or inthe event of the anchors becoming so tightly locked in the water-bedthat they cannot be lifted by the hoisting apparatus.

The invention has for its object to provide a simple and elficientarrangement for protecting the cutting blades from the water when theboat is submerged, and thus prevent themand their'operating parts frombeing impaired through rust.

The invention consists in providing a casing or housing for the cuttingblades, and in the peculiar and novel provision of a sleeve vention.

of lead or other soft metal providing a passage through the casingthrough which the anchor-cable operates, the said cutting blades beingso arranged to provide a shearing out upon the said sleeve and thecablewhereby the cable may be cut with the exertion of but little power.

The invention further consists in certain details of construction andnovel arrangements of parts as will be hereinafter described and thenclaimed. 4

In the drawings illustrating the invention, in the several figures ofwhich like parts are similarly designated, Figure 1 is a diagrammaticvertical longitudinal section of the forward end of a submarine orsulnnersiblo boat illustrating the a 'iplication'of my in- Fig. 2 is ahorizontal section drawn on a larger scale on the line a-a of Fig. 1.Fig. is a sectional view on the line 6-?) of Fig. 2, part of thesheaveover which the cable operates being broken away.

1 designates the forward end of a submarine or submersible boat havingan anchor well 2 arranged therein; and 3 desig- .nates thesuperstructure of the boat into which the upper end of the well 2 opens,these parts and general arrangement thereof being of the design commonin boats of the Lake type.

Upon the top of the hull plating and having an opening which registerswith the upper end of the well 2, is a casting -l upon which is mountedand secured in suitable manner, the base 5 of the lower half of asectional casing or housing 6, each section having an opening 8 in whichis held a sleeve 9, preferably of lead, but which may be of any'suitable soft metal. The said sleeve passes through the casing and hasits ends bent or flanged outwardly as at Sand designed to rest uponshoulders 10 surrounding the openings 8. The sleeve 9 is held in placeby nuts 11 which are threaded into the outer ends 12 of the openings 8,the

said nuts being provided with central openlugs and also with annularflanges 13 which are designed to fit into the respective ends of thesleeve 9, and also with knife edges 14:

'which are designed to engage and cut intothe flanges 9 of the sleeve 9so as to provide water-tight joints and thus prevent ingress of water tothe casing or housing 6 when the boat is submerged.

Journaled in bearings 6' formed in the upper and lower sections of thecasing G, is an idle shaft 15' a segmental worm gear 15 looselyjournaled thereon, the teeth of which are meshed'by a worm 16, carriedby a shaft 16 journaled in the casing 3, and having-one end extendedthrough the casing and provided with a bevel gear 17 which is meshed bya bevel pinion 18 carricd'at the upper end of a vertical shaft 19.journaled in a bearing '20 secured to the hull,

andin a stuflingbox formed in said bearing,

the inner end of the shaft bciug extended into the mum hull andprovided' with a hand wheel 21 as shown in Fig. l.

The segmental worm gear 15 is provided with an extension 22 having arecess 22 in which is securely held a cutting blade 23 having a curvedcutting edge as shown, and

secured to a boss :24 formed integral with having its inner cud. wounupon a drum (not shown) which may be of any suitable design, butgrcfc'rably of thc 'clesigm shown in Letiscrs stem No: Z 16 ,059gcsnitcd to Simon Lake, December 16. will?
